lambertian disibution, the use of non-axis symmeic xy direction free surface with the second optical light design can effectively solve the seet light type, light efficiency, uniformity, light disibution angles, glare, and security issues, consistent with national standards to provide the required light disibution, the real environmental and green lighting. the second total reflection can be achieved using optical lens with high optical efficiency, get more than 90% of the output efficiency. total reflection on the surface of the lens "w"-type surface, the direction of the road can be designed with light curve of the bat wing, to achieve good uniformity. condenser lens to the bottom of the non-spherical cylindrical lens to complete the design by the zemax, the total reflection surface and the outer surface of the free surface is accurately calculated from the mathematical model. display board (http://www.advertiseall.com/)smic beijing's 300mm new plant consuction and new technology development, production capacity in the short term from the current 20,000 and gradually expanded to 45,000. smic recently with the ip provider virage logic and synoys ip cooperation agreement was reached, respectively, hope to 65nm and below process technology to win more market share. as the indusy's benchmark 9 tsmc also announced jointly with fudan university and the icc for 65nm development. although tsmc and other factors affected by policy, not in china for large-scale and advanced foundry, but by walking and university cooperation and the production of the road may well be good policy. the establishment of china power microeleconics recent highlights, it chose a technology platform from imec.imec with china last month to force microeleconics 65nm cmos chip technology cooperation agreement was formally signed. led sign (http://www.advertiseall.com/)however, since sapphire, high hardness, elecical conductivity and poor thermal conductivity because of post-processing and application of the device bring a lot of inconvenience, sic there are also high hardness and the inadequacy of expensive, but relatively inexpensive si subsates have a good because thermal conductivity and mature processing technology and other advan***es of the device, so si subsate gan-****d led manufacturing technology by the indusy's attention. 1 si subsate led chip manufacturing technology road 1.1 si subsates in gan, blue led chip production. process: the growth of the si subsate on the growth of aln buffer layer process uses low-vol***e thomas swan ccs mocvd system in the 50 mm si (111) mqw grown on gan-****d suctures. using imethyl gallium (tmga) as the ga source, imethyl aluminum.menu board (http://www.advertiseall.com/)
